Electric toothbrush magnetic levitation acoustic motor



 Electric toothbrush magnetic levitation acoustic motor

        

       · Under rated current condition: Max 650ma ± 10%


       · Rated load swing angle: 20±5°


       · Temperature rise (ambient temperature less than 30 ℃): Less than 50K


       · Service life: Intermittent operation, cumulative not less than 200H (less than 50 minutes for each operation)


       · Locked rotor current: Maximum 1700ma (no more than 3 seconds)


       · Insulation resistance: The minimum resistance between motor terminal and metal shell is 1.0 m Ω / dc100v


       · Swing angle of motor shaft: Taking the frequency and current range in standard working conditions as reference, the maximum swing angle of motor shaft in practical application is ± 15 ° (0 ° for shutdown), and the motor noise will exceed the standard when it is greater than ± 15 °. It is forbidden to twist the motor shaft with a torque greater than 2kg / cm If it is over ± 15 degrees, the internal parts of the motor will be damaged and it will not work normally.


· Continuous running time of motor: After the motor runs at the maximum current for 50 minutes, when the temperature reaches or exceeds 80 ℃, the magnet performance will decrease by 2% - 10%, and the swing angle and force generated by the motor will be reduced


· Use of motor power line: When the motor wire is fixed with the circuit board after welding, the motor rear cover shall be taken as the starting point. The connecting wire within the length of 20 mm shall be in the state of free relaxation, and shall not be in the state of tension, compression or other stress
